5/5 Zenith 2
The leaks are only due to faulty or fake coils, faulty/fake coils have a common characteristic, they screw in CROOKED.
So when you notice that the tank doesn't screw in straight but wobbles, stop right there because it will most likely damage both the tank and the mod. The chances of faulty coils have almost disappeared by mid-2023, but whoever finds themselves in an unpleasant situation, return them to where you bought them to have them replaced.
Personally, only the 0.8ohm coils (at 17 watts) are worth it in terms of flavor, lifespan (10+ days), consumption, and overall MTL experience.... I only leave 1 hole open for flavor and throat hit (anything above 2 open holes ruins the entire MTL experience and is not suitable for these coils, only for the 0.3...), and I always wipe or rinse the base that regulates the airflow internally every time I change the coil because over time some moisture accumulates.
The device is worth it in every aspect, especially in terms of ease of use.

After changing atomizers of other companies every 6 months, either because they were leaking or because the glass was cracking/breaking after falls, I bought the Innokin Zenith 1 mainly because of its construction, which seemed like it would withstand falls.

This happened 5 years ago, 5 whole years the Zenith 1 endured dozens of falls without losing its color or performance in the slightest over time.

Since it was 4ml and seeing that the company released the Zenith 2 with 5.5ml, I proceeded to purchase it 3 months ago to take advantage of the additional capacity. The performance is the same, the protection is the same, and I am equally satisfied with my purchase.

Because many mention leaks, let me tell you, after 5.5 years of use, 9 out of 10 times when it leaked, it was my fault. It will leak when, after filling it, I take a puff with the filling port open (because I forgot to close it), then yes, liquid will run out of the air holes, which is normal. Apart from this type of leakage, which if not noticed can stain clothes, sheets, etc., and is the user's responsibility, in very rare cases, I may notice moisture on the outside, which means there was a minimal leakage that I don't know what causes it, I wipe it off with a piece of paper, and that's it.

I have had this particular vaporizer for 5 months now. I can say that it is possibly the best non-rebuildable vaporizer I have ever tried.

In terms of durability, it has taken quite a few falls and hasn't suffered any damage. Its color has not faded at all. Only the rubber seal on the filling port has torn slightly, which is not a problem (so far).

In terms of capacity, it is the best. The 5.5 ml speaks for itself. For normal MTL use, one fill is enough for over a day.

As for the airflow, there is no way someone won't find a setting that suits them. The 3 small holes are tight enough and ideal for a rolled cigarette, while the large slot, combined with the 0.3 ohm coils, allows for the option to play around with Restricted Direct Lung if one hasn't tried it before. My personal airflow setting is all holes open and the large one slightly open for MTL.

The MTL drip tip it comes with, in my opinion, is not satisfactory. Fortunately, I have the drip tips from the ARES 2. If someone doesn't want curves on their drip tips, they will be satisfied. The RDL drip tip it comes with is great.

The filling method is a bit annoying. It can be filled without removing the drip tip, but I don't recommend it. I take it out with my mouth, fill it, and put it back in place. A very minor issue.

As for the coils the company provides, I have tried 3. The 1.2, the 0.8, and the 0.3. Unfortunately, the 0.3 is the only option for RDL. I only used the one that came in the box, and I can say it was decent. I can't speak for maximum usage time because I changed it after 2 days along with the e-liquid. I would avoid the 1.2. After some research and personal use, I realized that it is very likely that they are all defective. All the ones I tried (3 in total) and ones my acquaintances tried produced a cotton taste. It's like the liquid doesn't pass through at all. Stay away. The best coils for me by far are the 0.8. They have great durability and the flavor is close to rebuildable. As a vaper, I am a chain vaper (as a smoker, I used to smoke a cigarette every 1.5 to 2 days). I need about 8ml of MTL vaping per day. Each coil lasts me 5 to 6 days. I change it at around 2500 puffs because it starts to produce a burnt taste. For someone who vapes "normally," each coil can last them over 10 days.

And now, the issue of leaking... I understand that many of you are hesitant about this particular vaporizer because you read about leaks. I have experienced exactly 0 leaks in the 5 months of use. If the coil is installed correctly (aligning the notches of the coil with the base), if the coil has its rubber seal, and if none of the internal rubber seals are missing, then there is no chance of leaking. If there is no rubber seal on the replacement coil, then it will release all the liquid through the airflow holes. If none of the rubber seals are missing, the coil is installed correctly, and there are still leaks, then there are 2 possibilities: a defective vaporizer, which is unlikely in my opinion, or a non-genuine/defective coil.

I used to vape only on rebuildable atomizers (Berserker, ARES 2, Wasp Nano & Fuji single), and since I bought this one, I never thought about changing it. It's worth it 100%

Five years of vaping, Cubis Pro vaporizers (don't even think about it, they're garbage), now Zenith 2 is my main vaporizer.

After two weeks of full use, I haven't found anything negative yet, okay, except for the fact that I have to remove the drip tip first in order to fill it, otherwise my bottle nozzles (different sizes) don't reach, but that's not a big issue.

Compared to the Zenith 4ml, I prefer it for its larger capacity and the fact that it completely disassembles, making it easier to clean, as well as the fact that I can adjust the airflow exactly as I want since it has a much wider range than the Zenith 4ml (for me, it's a bit tighter than I would like).

Other than that, it functions properly, no leaking or gurgling, solid construction, easy filling.

I haven't seen any leaks so far, just need to be a bit careful when screwing and unscrewing it on mods so that the bottom part doesn't loosen or unscrew (which obviously would lead to leaks).

I use them (I now have two, they have been very convenient for me) with Geekvape Solo 100W, Geekvape S100 (Solo 2), and Lost Vape Grus.

P.S.: I vape with Zenith coils 1.6Ω, 50-50 VG/PG

An excellent MTL vaporizer. Clearly improved in every aspect compared to the original ZENITH and slightly better in flavor than the ZENITH PRO for MTL vaping. I can't say for tight lung hits because I don't belong to that category. I would say it's on par with the ZLIDE, which I consider a top MTL vaporizer. The ZENITH/ZLIDE series coils require some special handling. I use the 1.2 Ohm coil, which is the most "difficult," but for me, it's unbeatable in flavor. I place it in the vaporizer and after filling it, I let it sit for two days without using it (obviously, I switch to other vaporizers). I start vaping at 10 Watts and then increase to 10.5. I gradually increase it by 0.5 Watts until reaching 12.5. The maximum flavor is achieved at 11-12 Watts. The 1.2 Ohm coils last me at least 7-8 days using this method. I change them every 7 days for hygiene reasons. The 0.8 Ohm coils last much longer and are preferred by most people, but I stick with the 1.2 Ohm because I enjoy vaping at low Watts.
